Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.

SUMMARY:

We are revising an earlier proposed airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The NPRM proposed to require modification of the anti-collision light bonding. The NPRM was prompted by a report of an in-flight lightning strike to the WHELEN anti-collision light located on the top of the vertical fin tip that caused severe damage and resulted in the loss of some airplane functions. This action revises the NPRM by clarifying the applicability. We are proposing this supplemental NPRM (SNPRM) to prevent loss of electrical power and essential airplane functions, and possible reduced control of the airplane. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

DATES:

We must receive comments on this SNPRM by August 1, 2016.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The NPRM published in the Federal Register on September 24, 2015 (80 FR 57545) (“the NPRM”). The NPRM was prompted by a report of an in-flight lightning strike to the WHELEN anti-collision light located on the top of the vertical fin tip that caused severe damage and induced the loss of some airplane functions. The NPRM proposed to require modification of the anti-collision light bonding.

Actions Since Previous NPRM Was Issued

Since we issued the NPRM, we have determined that we inadvertently referred to specific service information to identify affected airplanes in figure 1 to paragraph (c) of the proposed AD (in the NPRM). In order to clarify the applicability and identify the affected airplanes as specified in European Aviation Safety Agency (EASA) Airworthiness Directive 2015-0006, dated January 15, 2015, we have removed references to specific service information from the applicability of this proposed AD.

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0006, dated January 15, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The MCAI states:

An occurrence was reported where a Falcon 2000 aeroplane experienced an in-flight lightning strike, which caused severe damage and induced the loss of some aeroplane functions. The investigation results revealed that the entering point of the lightning was at the WHELEN anti-collision light located on the top of the vertical fin tip.

When the lightning strike hit the anti-collision light, an electric arc occurred between the aeroplane structure and the anti-collision light and created a conductive path by which the lightning current entered inside the aeroplane. Further analysis has determined that the electrical bonding between the WHELEN anti-collision light, Part Number (P/N) 01-0790044-09, and the fin tip fairing or the No. 2 engine air intake cover is insufficient to withstand a lightning strike.

In case of severe lightning, this condition, if not corrected, could lead to an unsafe condition (loss of electrical power and/or of essential functions) possibly resulting in reduced control of the aeroplane.

To address this potential unsafe condition, Dassault Aviation developed a modification (mod) to improve the WHELEN anti-collision light bonding when the anti-collision light is located on top of the vertical fin tip or on No. 2 engine air intake cover, and issued several Service Bulletins (SB) to modify all affected aeroplanes in service.

For the reasons described above, this [EASA] AD requires modification of the anti-collision light bonding.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-3629.

Related Service Information Under 1 CFR Part 51

Dassault Aviation has issued the following service information.

  • Dassault Service Bulletin F50-481, Revision 1 (also referred to as 481-R1), dated January 26, 2015.
  • Dassault Service Bulletin F900-372, Revision 1 (also referred to as 372-R1), dated January 26, 2015.
  • Dassault Service Bulletin F900-378, Revision 1 (also referred to as 378-R1), dated January 26, 2015.
  • Dassault Service Bulletin F900EX-285, Revision 1 (also referred to as 285-R1), dated January 26, 2015.
  • Dassault Service Bulletin F900EX-305, Revision 1 (also referred to as 305-R1), dated January 26, 2015.
  • Dassault Service Bulletin F2000-337, Revision 1 (also referred to as 337-R1), dated January 26, 2015.
  • Dassault Service Bulletin F2000EX-108, Revision 1 (also referred to as 108-R1), dated January 26, 2015.

The service information describes procedures for modifying the anti-collision light bonding. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Comments

We gave the public the opportunity to participate in developing this proposed AD. We considered the comments received.

Request To Address the Original Grimes Anti-Collision Light Installation

An anonymous commenter stated that the NPRM should address the original Grimes anti-collision light installation. This commenter asserted that any aircraft with the original Grimes anti-collision light installation would still be vulnerable to inadequate bonding.

We acknowledge the commenter's request. However, we are not aware of an unsafe condition associated with the original Grimes anti-collision light installation. We have determined that an unsafe condition exists on WHELEN anti-collision light installations and must be addressed. If we determine that an unsafe condition exists in the Grimes anti-collision light installation, we might consider further rulemaking. We have not changed this SNPRM regarding this issue.

Request To Reference the Revised Service Information

NetJets Aviation requested that we revise the NPRM to refer to revised service information for the actions specified in paragraph (g) of the proposed AD (in the NPRM). NetJets Aviation stated that all service information identified in paragraphs (g)(1) through (g)(7) of the proposed AD (in the NPRM) have been revised.

We agree that this SNPRM should refer to the most current service information. We have changed paragraph (g) of this proposed AD to refer to the revised service information. We have also added a new paragraph (h) to this proposed AD to provide credit for actions done “before the effective date of this AD” using the originally referenced service information. We have redesignated subsequent paragraphs accordingly.Start Printed Page 39599

Additional Change Made to This SNPRM

We have retitled table 1 to paragraph (c) of the proposed AD (in the NPRM) to figure 1 to paragraph (c) of this proposed AD to meet the requirements of the Office of the Federal Register. This change is for formatting purposes only.

FAA's Determination and Requirements of This SNPRM

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs.

Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM.

Costs of Compliance

We estimate that this SNPRM affects 778 airplanes of U.S. registry.

We also estimate that it would take about 12 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $801 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $1,416,738, or $1,821 per product.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. “Subtitle VII: Aviation Programs,” describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in “Subtitle VII, Part A, Subpart III, Section 44701: General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this proposed regulation:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and

4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
